A variation of the Everlasting Cross is the braided Carolingian Cross, named after the Carolingian dynasty, a Frankish noble family that can be traced back to the 7th century.
From the 3rd century, the Franks were a West Germanic tribe who lived north and east of the Lower Rhine River. By the 5th century, their influence had spread into Roman territory and Gaul, which probably explains why their art has stylistic similarities with pre-Christian Celtic knotwork.
The name 'Carolingian' stems from 'Charles', the first ruler (Charles Martel).
Coincidentally, the cross has a similarly sounding name to Cardinham Cross, an ancient Celtic Cross found in the walls of the 15th century village church of Cardinham, near Bodmin, Cornwall, England. This Cardinham Cross incorporates the Carolingian design.
There are a couple of ways to make a Carolingian Cross:
One way is to link four C's and connect the adjoining C ends.
Alternatively, four Triquetras can be connected together.
